Concern about wayspots for Yare Valley Walk

I came across a wayspot during review that looked OK at first sight, but was a little suspicious. As there was no streetview, I investigated further. The wayspot is a marker for the Yare Valley Walk.

Lots of surrounding wayspots are for other markers for the same named trail, but none of them are on the official route of the walk. They are all on non-streetview locations. Also, the markers are all fixed to random objects without nails or staples or pins or anything. Lots of them are post-Ingress so don’t appear on intel. They feel slightly /wrong/.

Is there anyone in this area that can physically check them out?

Sorry not in that area.
Typically a route like this will be based on a PROW


Costessey BR3 is the key bridleway through that area
That line seems to fit with the sequence of wayspots.
I think this is a case of needing a visit to check. There should be bridleway signs.
